Can I teach myself CAD?

The three letters of CAD mean computer-aided design. What is computer-aided design? The function and history of CAD can be found on the Internet, so I won't go into details.

Personally, I simply think that CAD is drawing software, which can draw complex engineering drawings instead of simple lines or icons. Its drawing function is very powerful and almost omnipotent. So, if you draw mechanical drawings, architectural drawings, electrical drawings, etc. Using CAD is the best choice.

There are three kinds of graphics drawn by CAD: plan, axonometric and stereoscopic. The pattern is as follows.

Plan: This is a mechanical part drawing drawn by students, which is called a part drawing. There are graphics, dimensions and technical requirements. , and a table in the lower right corner called the title bar. It is very convenient to draw such a picture with CAD, and a skilled draftsman can finish it in half an hour. If it is hand-painted, it will take several hours, and hand-painting is not very accurate.
